An Easier, Cheaper and More Comfortable Way To Take Zytiga

Rather than taking – and paying – for the full Zytiga dose on an empty stomach, ask your doctor if you could get the same effect from taking just one fourth of your Zytiga dose while enjoying a low-fat or high-fat breakfast. A small phase two study of 36 prostate cancer patients who took 250 mg of Zytiga after a low-fat breakfast had almost the same outcomes as 36 other prostate cancer patients who took the regular 1000mg dose on an empty stomach. These 72 patients were from the United States and from Singapore. Their age rage was from 52 [...]

Ask For a Blood test to identify AR-V7 in Circulating Tumor Cells if you are starting Xtandi or Zytiga

One of the hot topics in the prostate cancer community is the value of detecting AR-V7 tumor cells circulating in the blood. AR-V7 tumor cells in the blood predicts response or failure of treatment with enzalutamide (Xtandi) or abiraterone (Zytiga). A recent study found that men who have AR-V7 circulating tumor cells in their blood will not respond to Xtandi or Zytiga and will live longer if treated with a taxane based chemotherapy (docetaxel) regimen. A study in JAMA Oncology, showed that evaluating for the presence of circulating tumor cells (CTCs) with AR-V7 could optimize treatment protocols. The study looked at 161 men with progressing metastatic castration-resistant [...]

Xtandi In Combination with Zytiga Is Not Better Than Either Drug Alone

Often I have heard people ask why if one drug is effective we shouldn’t simply take two or three at the same time? The answer is simple, because we don’t know if combining multiple drugs will make any difference to a man’s survival. The only way we can be sure is with good evidence. Good evidence requires, in the case of drugs, doing a clinical trial to see if a certain type of combination will be beneficial. In such a late-stage clinical trial designed to see if Xtandi in addition to Zytiga along with a steroid worked any better than [...]

Cognition and Hormone Therapy (ADT)

There have been numerous studies examining the how hormone deprivation (ADT), in the treatment of prostate cancer, has on a man’s cognition. There have been contradictor studies about this issue, however having had the experience and the honor of dealing with so many men with prostate cancer treated with androgen deprivation therapy (ADT), as well as my own personal experience, I must fall in line and agree with an online published study that shows that men on ADT are likely to experience cognitive impairment of some type. The study was small, as all of the other studies have been, followed [...]
